Iran Press/Iran news: Donald Trump and First Lady Melania Trump are meeting the Queen on Monday on the first day of their state visit to the UK.
The pair are at Buckingham Palace for a private lunch and welcome ceremony, the Independent reported.
Mr and Mrs Trump arrived on Air Force One earlier on Monday and were taken to the US ambassador's home in central London, where they are staying.
Minutes before touching down, Donald Trump criticised Mayor of London Sadiq Khan, with whom he has clashed in the past.
He tweeted that Mr Khan - who had earlier said the UK should "not roll out the red carpet" for Mr Trump - was a "stone cold loser", but the president added he was looking forward to his visit.
Protests are planned in several UK cities during the three-day visit, including London, Manchester, Belfast, and Birmingham.
It happens just a year after the giant "Trump Baby" blimp sparked controversy in London.
However, Donald Trump has rejected that he is unpopular in the UK, saying he believes he is 'loved' by the British people as he prepares to start a three-day visit. The American president, whose mother was born in Scotland, claimed he had a closer relationship with Britain than any former resident of the White House.
Talks between Donald Trump and outgoing Prime Minister Theresa May will begin on Tuesday, with the pair expected to discuss climate change and Chinese technology firm Huawei.
When Donald Trump traveled to Britain last year he avoided London, where an estimated 250,000 people marched against him.
